' Be it known that LJosnrH VAN ACNNREN, a` citizen of the 'United IStates, 'residing in Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented anew andfuseful Improvement in Standpipe A -pparatus, of which the following is a specifi-v cation. E .v y

' The object. of thisinvention is to provide an improved,standpipel construction for the discharge of the distillation' products from carbonizing plants, such 'as byproduct coke oyen plants of the Koppers cross-regenen,

' -ative type exemplified in ,theprior Letters 'Patent' of Vthe United States oi Joseph Becker, for coking retort oven, No. 1,374,546, granted April 12, 1921. According to the invention, provision is made for directly spraying these-ating portion of the body of the valve between' the standpipe' and the collecting main, and also the gases'before they reach the collecting main, without any Y danger whatever of the spray entering the such otheramprovements or advantages in iso coking chamber orretort. Provision is also made for .the spray to descend vertically on van upwardly presented and preferably cupped valve body, around which it flows off to or into the collecting main, and this man ner of spraying the valve body is particularly facilitated by locating .the valve at the bottom of a. discharge pipe that descends.l

.frein-and 1n proximity tothe riser pipe.

' There' is `furthermore provided an improved form O15-,connection between lthe s'tandpipe apparatus and the collecting main, whereby the spray liquor .is compelled to flow into the bottom of the collecting main, from whichthe liquor may be discharged and disrecovery of ammonia and tar. .d .n In addition to thegeneral ob]ects recited above, the'invention has for further objectsA construction'and operation as may be found to obtain'in the structures and devices hereinafterdescribed or-claimed. 'lin the accompanyingdrawings orminga part of this specification and .showing for purposes of exemplifi'cation a preferred' form andA manner in whichthe invention may j be embodied and practiced, but without limi/ tosed of `in asubsequent Itreatment for the PENNSYLVANIA, assreNoa To THE xori :Ens COMPANY, orrrr'rsnunen, rnNNsYLvaNiA, A CORPORATION or PENN- 13, 1923..

illustrative instance or instances:

Figure 1 is an elevational view'of a standpipe apparatus constructedv in accordance with the invention, the view showing the apparatus applied to the gas outlet of one of ythe coking chambers ot a colring retort oven. and connected with a collecting main in which the gases and distillationproducts of a' battery ot` coke ovens are collected and i ing the claimed invention specifically tosuch subsequently discharged to the by-product recovery apparatus. y

Fig. 2 is atop planview of the apparatus;

and Fig. 3 -is a vertical sectional view 'of the same.- v Y The same characters of reference designate the same parts in each of the several views vention there is shown afragment cfa coking chamber 11 provided in.- the top'12 with a gas outlet 13 through which dischargel set' forth4 in the prior patent of Josephv Becker No. 1,374,546, hereinbefore men- -tioned. The discharge outlet- 13 of each coking chamber- 11 is equipped with alstandpipe apparatus, and the standpipes of the several colringchainbers are connected with and discharge into a -cornmon'collecting main 14 which extends along one 'side of the batl tery. The collecting main 14 maybe providedat one end with an elbow 15 `or connecting-said main to .the gas pipe through which the gases and other products pass to .the by-product recovery apparatus.v

In' accordance withl the invention, the

standpipeapparatus includes a riser ypipe 16 constituted, preferably, oi a lower. vertical pipe sectionl( mountedfdirectly over the gas. outlet-13 and" from which the gases and;

distillation products pass'into an upper vertical pipese'ction 18 set. in the top ofthe lower section-'17.. At the top of the upper sis aisl

section 18 thereis vprovided an inspection` hole 19 normally closed bythe pivoted'manw. ally-operable cover 20.. 7 l. VFrom tl-1e .top fof. the "priser .pipe 16"' the I "ib In Vthe illustrated embodiment of the i'n'- 45 A valve closing position the liandley29 may be hooked under a lug 30 .projecting from the gases pass into the downwardly curved up# lower discharge pipe section 22 of each standpipe apparatus is connected by a short pipe section 23 with the side of the collecting main, the connecting pipe 23 .being preferably located near the bottom of the collecting main, as shown, and below the longitudinal axis of said main. Referring more particularly to Fig. 3,`the

' upper dischargek pipe section 21 is providedv with a tapered port-i011 24 which projects within the inclined discharge section 22 and provides a seat 25 for a drop valve 26. The valve body 26 may be of the dished plate type, with the concave surface uppermost, so that, whenliufted to closed position, the tapered portion 24 enters and seats securely within the concave upper surface of the valve body though permitting an overflow of sealing and cleansing liquid around Ithe periphery of said-body, as hereinbefore set forth. The valve body 26 'is mounted by ears 27 on a rock shaft 28 which projects through the discharge pipe section 22 and is 1provided at vits outer end with .an operating handle 29. The handle 29 is lifted to lower the Vof pipe section -21- and just over the valve 'tin -maijh This is usually done at the time of charging the corresponding coliing chamvalve into open position and lowered, as shown by dot and dash lines -in Fig. 1, to lift the valve intoclosed position for shutod the standpipe from the collecting ber or pushing out the eolie. Whenl in the side of the riser pipe 16, in order to hold the valve body 26 up securely against the seat ilhe above described construction provides an extremely simple and economical .means for permitting the gases and the' valve body itself to be sprayed, without anydanger of the spray liquor 'entering the riser pipe'andi falling into the coking chamberjor retort. The spray liquor may be introduced into' the gases as they `pass downwardly through the.

discharge g pipe sections 21 and 22 from a nozzle 31`set into a port 32 located in theI fop *Y body 26.I When the valve 26 is open the spray from the nozzle 31 will thoroughly' flush out the concave" upper surface o `the y.valve body and will discharge through the .connected pair of discharge lateral connections 22 and 23' directly intoT the bottom of a collecting main 14.y
